Multilayered screening for multi-targeted anti-Alzheimer's and anti-Parkinson's agents through structure-based pharmacophore modelling, MCDM, docking, molecular dynamics and DFT: a case study of HDAC4 inhibitors.

Abstract: Alzheimer's disease (AD) and Parkinson's disease (PD) are neurological conditions that primarily impact the elderly having distinctive traits and some similarities in terms of symptoms and progression. The multifactorial nature of AD and PD encourages exploring potentiality of multi-target therapy for addressing these conditions to conventional, the "one drug one target" strategy. This study highlights the searching of potential HDAC4 inhibitors through multiple screening approaches.

Unraveling the synthetic strategy, structure activity relationship of azetidinones: Insights into their multidrug and toxin extrusion protein (MATE transporter) inhibition facilitating drug development against MDR.

Heterocyclic chemistry gathered a wide audience due to their presence in potential drug candidates and being attractive synthons initiating several retro-syntheses the organic as well as in medicinal chemistry fields. Among them, azetidinones have been a subject of discussion due to their serendipity, curiosity, versatility by Penicillin and Cephalosporins as β-lactam antibiotics. Despite possessing a large margin of biological activities, azetidinones mainly work as antimicrobial, interfering with bacterial cell-wall synthesis blocking transpeptidase.

Fully automated radiosynthesis of [F]FCPPC for imaging microglia with PET.

Colony-stimulating factor 1 receptor (CSF1R) is almost exclusively expressed on microglia in the human brain and thus, has promise as a biomarker for imaging microglia density as a proxy for neuroinflammation. [C]CPPC is a radiotracer with selective affinity to CSF1R, and has been evaluated for in-human microglia PET imaging. The flourine-18 labeled CPPC derivative, 5-cyano-N-(4-(4-(2-[F]fluoroethyl)piperazin-1-yl)-2-(piperidin-1-yl)phenyl)furan-2-carboxamide ([F]FCPPC), was previously synthesized, however, with a low radiochemical yield using manual radiosynthesis.
